Today, Sony officially announced the upcoming release of the LYTIA 720, an approximately 50-effective-megapixel image sensor for mobile applications that delivers industry-leading low-light performance and supports 4K 60fps HDR video recording.
50MP Sony LYTIA 720 image sensor
Designed for use on the main camera of mobile devices, the new sensor inherits technologies developed for Sony’s LYTIA high-end series. Sony’s proprietary low-noise circuit technology reduces random noise in dark environments by approximately 50% compared to a conventional product while achieving a dynamic range of 100 dB through HDR compositing technology.
By optimising AD conversion circuits, the new sensor supports 4K 60fps video recording with all-pixel autofocus while HDR is enabled. The new sensor offers high imaging performance in a 1/1.56-type size, which is being widely adopted in the smartphone market.
Main features
- Proprietary UHCG circuit technology delivers industry-leading low-light performance: Ultra High Conversion Gain (UHCG) circuit technology that achieves high charge-to-voltage conversion efficiently surpasses image grain caused by noise in dark environments.
- Optimised AD conversion circuits enable 4K 60fps HDR video recording with all-pixel autofocus: This is the first 1/1.56-type LYTIA product with a 1.0 μm pixel size to support this feature. Additionally, using single-frame HDR technology for 4K 60 fps HDR video recording suppresses motion artifacts while maintaining sufficient exposure time for low-noise imaging.
- Hybrid Frame-HDR technology delivers a 100dB dynamic range: This technology combines Dual Conversion Gain- HDR with frames recorded at short exposures. HF-HDR technology combined with UHCG circuit technology delivers a dynamic range of 100dB. This enables imaging that more closely resembles what the human eye perceives, with reduced loss of detail in shadows and highlight blowouts even in high-contrast scenes.
